Each surgical operation is followed by a series of inflammatory and metabolic changes that constitute the stress response.

Laparoscopic approach to a large adrenocortical oncocytoma: A case report and review of the literature.

Introduction: Adrenocortical oncocytomas are extremely rare tumors, considered to be non-functional and of low malignant potential. Despite the great advance in laparoscopic techniques, there are extremely limited reports of laparoscopic approach of adrenocortical oncocytomas. Herein is presented a challenging case of laparoscopic approach to a large adrenocortical oncocytoma, underlining the safety and feasibility of laparoscopy in the surgical management of these extremely rare adrenal tumors.
